Excelitas expands silicon enhanced APD line
The high-performance based avalanche photodiodes are designed for ultra-low light applications
Excelitas Technologies has announced the availability of an enhanced series of avalanche photodiodes (APDs) that provide high-responsivity for ultra-low light applications. Featuring a double-diffused "reach-through" structure, the C30902EH-2 and C30902SH-2 APDs are fabricated with a built-in 905 nm band pass filter for high efficiency and rapid rise and fall times. The modules can be used in normal linear mode or in "Geiger" mode, to meet customers' specific needs in LIDAR, range-finding, small-signal fluorescence, photon counting and bar code scanning applications. "We are continually integrating industry-leading innovations and enhanced features such as a wide operating range and extremely low noise to our wide range of photodiode solutions," says Michael Ersoni, Executive Vice President, Global Commercial Business, Excelitas Technologies. "Excelitas' latest silicon APDs with integrated filters are an excellent option for OEMs seeking photon detectors that will increase the efficiency and performance of their end-products." The EH-2 version's low-level light and advanced signal detection capabilities are further enhanced by a hermetically-sealed TO-18 package that enables minimal signal losses without the risk of endangering detector stability. Both modules offer high quantum efficiency (77 percent typical at the 830 nm wavelength) and rapid spectral response in the 400 "“ 1000 nm range. The C30902EH-2 and C30902SH-2 modules are on display at Photonics West, taking place in San Francisco, from February 4th to 6th, 2014 at the Excelitas Technologies booth #5509.
